We need to reduce light pollution

Light pollution is an issue that not enough people worry about. As an amateur astronomer and an astronomy student, I am noticing firsthand how light pollution interferes with stargazing and astronomical studies. When there’s too much light at night it brightens the atmosphere which makes all stars, and planets, dimmer and harder to see. Not only for my discipline but light pollution harms nocturnal species. Nocturnal animals rely on darkness to hunt, migrate, and survive. When skies get brighter because of harsh lights, Earth’s wildlife is harmed.

We need more cities to use warm-toned, motion-censored streetlights, with proper shields, so light only shines downwards. Additionally, for people to be aware that leaving excessive lights on is harmful and that warm lights are recommended. Solutions like these will safeguard astronomical research and reduce light pollution that affects wildlife and ecosystems on Earth. While there may be technical and financial challenges, the benefits of darker skies will improve scientific research, and animal-life, making this a necessary step forward.

I urge you to contact your legislators to promote Dark Skies acts and bills and to turn off your lights.
